We look at the division of 938586 by 23 
Let's see how many times 23 fits into 938586.

On to step 1:
9 divided by 23 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 23

Let's proceed to step 2:
When dividing 93 by 23, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 92 from 93 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 23

Going ahead to step 3:
When dividing 18 by 23, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 18, we end up with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 23

Step 4:
185 divided by 23 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 408.0
Subtracting 184 from 185 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 23

On to step 5:
When dividing 18 by 23, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 4080.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 23

On to step 6:
If we divide 186 by 23, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 40808.0
Subtracting 184 from 186 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 23 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 40808.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 40808.08
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
If we divide 160 by 23, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 40808.086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 23, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 40808.0869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
23 goes into 130 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 40808.08695
Deduct 115 from 130 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
23 goes into 150 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 40808.086956
If we take 138 away from 150, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 40808.0869565
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
If we divide 50 by 23, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 40808.08695652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 40808.08695652 with a remaining 4e-09.
